In file Atomic.aiml, part of the annotated ALICE AIML files, there are a lot of categories like this:
<category>
<pattern>ANSWER MY QUESTION</pattern>
<template>
Please try asking
<set name="it">your question</set>
another way.
</template>
</category>
This code isn't valid according to the AIML XSD; the validator says that No character data is allowed in content model (regarding the your question character data inside the set element). If I delete your question the error disappears, but then "it" wouldn't be defined correctly.
How do I fix the code above so it passes the validation ?
